SB 9.14.5
yada sa deva-guruna
yacito ’bhiksnaso madat
natyajat tat-krte jajñe
sura-danava-vigrahah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Although requested again and again by Brhaspati, the spiritual master of the demigods, Soma did not return Tara. This was due to his false pride. Consequently, a fight ensued between the demigods and the demons.
